The Juwella is a folding camera made by Balda in the 1930s. It makes 6×9 cm images (and some cameras can also be masked for 4.5x6 cm pictures; this was an optional feature) on 120 roll film. McKeown lists four generations of the camera, dated to 1933, 1936, 1938 and 1939. The first of these was at first named the Jubella for a short period, to celebrate Balda's 25th year (as the Jubilette was named for the company's 30th year in 1938); Jubellas are identified by the name impressed in the leatherette, and the lens has the same name.
The camera is self-erecting, with a button to release the front next to the film winding knob or key.
The lens is a fixed 10.5 cm f/6.3 or f/4.5 Juwella Anastigmat (or Jubella in the earliest cameras), with front-element focusing to about two metres. Many examples have an everset shutter with speeds 1/25 - 1/100 second, plus 'B' and 'T'; this may be Balda's own, or a Pronto, with the same speeds but also with a self-timer. McKeown states that better-specified shutters including Compur and Prontor II were available on at least the 1938 camera. A body-mounted shutter release button was an optional feature of the 1939 model,; however, some cameras from 1936 onwards have a curious clasp mounted on the front, just above the front door, which holds the end of a cable release (thus providing a body-mounted shutter release).
In most examples, the main viewfinder is a double frame type, with extra frames for the half-frame format on those cameras adapted for it. McKeown states that a reverse-Galilean finder was an option from 1938. There is also a Brilliant finder mounted on the lens standard, which swivels for horizontal and vertical use.
The earliest Juwellas have a film winding knob, which is replaced with a winding key in later models. the film compartment opens with a small sliding latch (marked with an arrow) by the carrying strap. In the back, there is a swing-out holder for the full spool; at the other end, the winding key must be pulled out to fit the take-up spool.
The camera has a ⅝-inch tripod bush.
